IMPROVEMENT IN STEAM-FLUE. CLEANERS.

Specification forming part of Letters Patent No. 210,833, dated December 17', 1878; application filed August 15, 1878.

To all whom it may concern.-

Be it known that I, ROBERT ATHERTON, of the city of Paterson, in the county of Passaic and State of Sew J crsey, have inventedanew and usefulImprovement in Steam-Flue Clea-n ers, of which the following is a specification:

Figure 1 is a plan view of my improved steam-flue cleaner. Fig. 2 is a longitudinal throughsection of the same. Fig. 3 is a reversed plan view of the conical fan.

Similar letters of reference indicate corresponding parts.

The object of this invention is to facilitate the operation of cleaning the fines of steamboilers at all times, when the same are carrying any desired pressure of steam, by means of attaching a suitable rubber tube to the T connection, said rubber tube being attached to a suitable pipe or connection in the boiler.

"he invention consists in the steanrchamher and fan-case consisting of the hollow chamber, perforated partition, and fan-case, in combination with the conical fan, spindle, and washer, extension-pipe, stopcock, T-conneo tion, and handle, as hereinafter more fully de scribed.

A is the steam-chamber. a. is the inlet to the same. B is the perforated partition (dividing the steam-chamber from the fan-case) through which the steam passes. I) is a hole in the center of the partition 13, which is tapped out for the reception of the spindle G. D is the fan-case, the outside edge of which is turned to allow the same to be easily inserted into the end of the flue, leaving a beadin g or shoulder, d, which, coming in contact with the end of the flue, allows the machine to be firmly held in its place, at the same time keeping the flue almost steam-tight, thereby preventing any waste of force. E is a conical fan, with blades or wings a set spirally.

The center of the cone E is bored out at one end, so as to revolve easily on the spindle (J, and at the other end is as much larger as may be desired. In the larger end is fitted a bush, F, the inside diameter of which corresponds with the diameter of the small hole, said bush being made the desired length and securely fittedin the cone E, and forms a recess, G, in

the center of the cone E, which serves as a reservoir for oil or any other lubricant, which is supplied through the oil-hole g in the face or front of the cone E.

The spindle G has a thread cut on one end, and near the'other end is a shoulder or collar, 0 between which and the face or front of the conical fan E is inserted a loose washer, 0 which relieves the collar 0 on spindle 0. Outside of the collar 0 on the spindle G is left a square, so that the spindle C may be readily tightened or loosened by means of a wrench.

H is the extension-pipe, (which may be of any desirable length for the convenient working of the machine,) one end of which is securely screwed into the inlet a of the stoma chamber A, and the other end is screwed into one end of the stop-cock I. In the other end of the stop-cock l is screwed one end of the T-connection J, and in the other end of the T- connection J is securely'screwed the handle K, leaving the remaining opening in theT-connection J for the attachment j to be properly connected with the boiler.

"With this construction the small end of the fan-case D is inserted into the end of the flue, with the beading or shoulder d firmly held against the extreme end of the flue, when, the proper connections having been made with the boiler, the steam rushes into the rubber tube and attachment j, T-connectiou J, and stopcock I. hen the handle t" of the stop-cock I is turned the steam enters the extensionpipe H, passing into the steam-chamber A, through the holes or perforations in partition B, to the faacase D, and, coming in contact with the conical fan E and spirallyset blades or wings 0, causes the same to revolve at an astonislr ing speed on the spindle C, and the steam which. escapes through the opening between the outside of the conical fan E and the inside of the fan-case D, by the action of the swiftlyrevolving conical fan E, rushes into the flue with an expanded. spiral and rotary force, causing the dirt in the flue to revolve with in ereasin g speed until forced out at the opposite end, thereby preventing any dirt from falling to the bottom of the flue while being cleaned. The steam is then turned off by reversing the 2 erase? handle 1' of the stop-cock Land the operation G, oil-hole g, the spindle O 0 loose washer c is speedily performed on the succeeding flue. the extension-pipe H, the stop-cock I i, T-

Having thus described my invention, I connection J, attachmentj, and the handle K claim as new and desire to secure by Letters with each other, arranged substantially as set Patentforth.
